Small Ship Cruises in Sullivan Bay

Sullivan Bay on Santiago Island is renowned for its geological value to the scientific community and the tourists who visit it. It holds a special place in history as the second of the Galapagos Islands visited by Charles Darwin.

Guests are invited to walk the hour-and-a-half path from the visitor’s center through the bay to marvel at the volcanic landscape created by long cooled lava flows from 1897. The formations underfoot simulate the waves in the sea and join together in both rope-like structures and rusty colored tuff cones.

Wildlife encounters at Sullivan Bay include the usual suspects in Galapagos, including boobies, tropical fish, and reptiles for which the islands are famous. This site is prized primarily for its unusual appearance and landscape, however rather than abundant animal life.

The white sand beach is a glorious visual contrast to the edge of the lava stream it borders. No adventure cruise to Sullivan Bay would be complete without swimming or snorkeling in the clear blue Pacific waters.

Top things to do and see at Sullivan Bay

Most guests visit Sullivan Bay to see the landscape and take the hour and a half hike over the plumes and pahoehoes created by flowing lava so many years ago. Hikers will appreciate the local vegetation including Molluga plants and the incredible view of the volcano that made the island itself.

After the hike it’s time for a swim or snorkel in the lava cape at Sullivan Bay. The setting makes the perfect photograph with the blue water, white sand beach, and dark volcanic landscape.

Top Tips for visiting Sullivan Bay

  • To get the most out of your trip to Sullivan Bay, here are some helpful tips.
  • Be sure you have some sun protection like sunblock or clothing that covers your skin. It’s important to be able to limit your sun exposure as necessary.
  • You’ll want some sturdy, adequate shoes for walking or hiking around Sullivan Bay. Blisters are not a part of this vacation. Bring along some water shoes as well for snorkeling.
  • To capture your Sullivan Bay wildlife encounters or a visual keepsake of the bay itself, bring a camera along. If you want to use a mobile device off of the ship, we recommend you protect it with a water tight sleeve and a dry bag during transport.
  • Visitors who want to scuba dive will have access to complimentary tanks, weights, and belts. If you have other equipment for scuba like a mask, you can bring it along or rent whatever you need onboard.
